Add native Playwright WebSocket sessions alongside the existing curated
browser tools. Agents can now create remote sessions that expose a full
Playwright API over WebSocket, enabling advanced use cases like HttpOnly
cookie injection, storage state management, and route interception.
Key changes:
- Per-bot isolated browser processes (launchServer via Node child process)
- New session module with create/close/status/heartbeat endpoints
- New browser_remote_session agent tool (Go)
- Storage state export/import on existing browser contexts
- Bot ID plumbing through context creation for process isolation
- Inflight deduplication to prevent duplicate browser launches
- Session janitor for automatic expiry cleanup
* refactor(browser): split browser cores via build ARG, add core selector
- Replace playwright official image with ubuntu:noble base in both
docker/Dockerfile.browser and devenv/Dockerfile.browser; install
browsers at build time driven by ARG/ENV BROWSER_CORES
- Add GET /cores endpoint to Browser Gateway reporting available cores
- Proxy GET /browser-contexts/cores in Go handler to Browser Gateway
- Add `core` field to BrowserContextConfigModel and GatewayBrowserContext;
context creation selects the appropriate browser instance by core
- Frontend context-setting page fetches available cores and renders a
core selector; saves core as part of the config JSON
- install.sh prompts for browser core selection and writes BROWSER_CORES
to .env; builds the browser image locally before docker compose up
- Regenerate OpenAPI spec and TypeScript SDK
* fix: lint
